Thank’s for sharing.
Actually bluetooth driver not include at Kubuntu, isn’t it..?
At ubuntu, with Gnome, bluetooth include.
Ugh…, it’s problem for me because I need that’s bluetooth to connect to the internet with my cellphone.
Not sure if 5 DVD repo Ubuntu have that driver…
I’ll try..
Once again, thank’s

I removed and reinstalled kdebluetooth, but now it doesn’t seem to start.
I can find it in the menu, but when I typ kbluetooth, or kdebluetooth or kdebluetooth4, I always get: “command not found”
when I try to activate it in the menu, it just won’t start.
any idea what i did wrong?
